Samoa Industrial double diaphragm pump DC20 1/4" acetal/PTFE DC20PDSTCTTBAS
|
Air-operated double diaphragm pumps for metering and transferring a wide range of fluids. For OEM applications and industrial processes with lower flow rates. The air motor with unbalanced control valve requires a lower starting pressure, which allows more accurate flow adjustment by regulating the air pressure. The pump's wetted materials are suitable for the most aggressive liquids and use in corrosive environments. The air motor (pneumatic directional control valve and air chamber covers) is made of polypropylene. Fully groundable pumps with ATEX certification are available for use in potentially explosive atmospheres (Ex II2 GD IIB/ IIC 95 ˚C).
Application area
ATEX pump. Solvents (most ketones, acetates, aldehydes,
aromatic and chlorinated hydrocarbons) solvent- and water-based
water-based flexo and gravure inks, varnishes and paints. |
